GFS Steel Water Tanks: Glass-Fused-to-Steel Water Storage for Municipal, Industrial, and Rural Supply

Water storage underpins every community and plant - the tank must stay potable-safe, corrosion-free, and serviceable for decades while fitting a site and a budget. Concrete needs liners and waterproofing repair; welded steel needs periodic recoating; plastic caps out at small volumes. The Glass-Fused-to-Steel (GFS) tank answers all three failings with a single inert, bolted, certified surface that the project can rely on from commissioning to replacement.

Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) builds GFS steel water tanks that fuse glass to steel at 820-930 degrees Celsius for an inert, certified, 30-50 year surface. As China's first GFS manufacturer since 2008 with nearly 200 enameling patents, the company supplies the 20-60,000 m3 GFS range to more than 100 countries.

A GFS (Glass-Fused-to-Steel) water tank is a bolted vessel whose steel panels are coated with glass fused at high temperature - creating one inert, impermeable surface.

• Fused, not painted: molten glass reacts with steel at 820-930 degrees Celsius, forming a bond of 3,450 N/cm2 that cannot peel.
• Inert and impermeable: the glass surface does not react with water and blocks moisture from the steel - no rust, no leaching.
• Bolted assembly: factory-coated panels bolt together on site with no welding and no field painting.
• Certified potable: NSF/ANSI 61 and WRAS certification qualify GFS for drinking water.

GFS serves the full water spectrum - from village supply to industrial process to fire reserve - on one durable platform.

• Municipal drinking water: city and village reservoirs, elevated and at-grade, certified for potable use.
• Rural and irrigation: farm and community water where reliability beats lowest first cost.
• Industrial process: process water, cooling, and boiler feed where purity matters.
• Fire protection: NFPA 22 / FM compliant fire reserves with a lining that never degrades in standby.

GFS wins on lifecycle: faster build, no recoating, and a certified inert surface that concrete and coated steel cannot match.

• Speed: bolted panels erect in weeks versus months of concrete or welding.
• No recoating: the fused glass lasts 30-50 years with no paint or galvanize renewal.
• Potable certainty: NSF/ANSI 61 and WRAS are built into the material, not added as a liner.
• Scalability: the 20-60,000 m3 range and parallel-tank option cover any community or plant.

Center Enamel GFS steel water tanks are FEA-verified to AWWA D103-09, manufactured under ISO 9001/45001, 100% high-voltage holiday spark tested at 1,500V, and certified to NSF/ANSI 61, ISO 28765, WRAS, and EN 1090 - supplied across the 20-60,000 m3 range to more than 100 countries.

A GFS (Glass-Fused-to-Steel) water tank is a bolted vessel whose steel panels are coated with glass fused at 820-930 degrees Celsius. The result is one inert, impermeable surface bonded at 3,450 N/cm2 that cannot peel or rust, certified to NSF/ANSI 61 and WRAS for potable water.

GFS serves municipal drinking water, rural and irrigation supply, industrial process water, and NFPA 22 / FM fire protection reserves. Its certified inert surface fits any duty from village supply to plant process.

GFS builds in weeks (not months), needs no recoating across a 30-50 year life, and carries NSF/ANSI 61 and WRAS in the material itself. Concrete needs a liner and waterproofing repair; welded steel needs periodic coating renewal.

Yes - capacity (20-60,000 m3), diameter-to-height ratio, roof type, lining grade (pH 3-11, 1-14 special), insulation, heating, and fittings are engineered per duty and site, certified and supplied to 100+ countries.

• GFS fuses glass to steel at 820-930 degrees Celsius for an inert, impermeable, 3,450 N/cm2 bond.
• One platform serves municipal, rural, industrial, and fire water with NSF/ANSI 61 and WRAS certification.
• GFS builds in weeks with no recoating and a 30-50 year design life.
• Center Enamel supplies the full 20-60,000 m3 GFS water tank range to 100+ countries.
